Looking for Francis Marion aka.J.M. Crow's grave site, Ky.

Francis Marion Crow, aka, Joseph Marion Crow was born in or near Antioch,Ky. in 1837. By 1850 he was(possibly) in Trenton, Gibson County, Tn. under the name J.M.(Joseph Marion) Crow.He was living with a family listed in the census as Worrington (probably Worthington).
In 1862 he was in Flatwoods or Linden, Perry County, Tn. In 1862 he married Rosana Matilda (Grimes birthname)adopted by Bill & Kate Flowers. My ggrandfather was born there in 1864. They later moved to White County, Ar. Joseph received news that his father was ill, so he traveled to ? Tn.or?Ky. to visit. My ggrandmother received that J.M. died there.
I have since found out per a letter written by his sister,Sarah Jane (Crow)Coulter, that he was buried near Willisburg, Ky. I am still looking for verification.
